No clue at all. I have directly compiled a hello world. Apart from trying a few other environments, all of my experience coding java is in Eclipse.
Notch described at one time the coding environment that he would set up a new employee with, and that he uses. All of it is free. Java, Eclipse, Paint.net, and Putty. I am not sure that Paint.net is the best and I think there are several systems that have advantages over Putty, but I am quiet well in love with Eclipse and I don't think I use even a third of it's capabilities.
I tried looking at tuts to Compile in Eclipse but the only info was to put to com folder with the images into the sidebar which didn't help at all.
I too made a HelloWorld.java, and compiled with javac, but it seems that when I try to compile the Minicraft files, it seems as if one file depends on another to be compiled.
If you find an extremely in depth tutorial for Eclipse, I'd love that, if not, I can continue through CMD and Compile 1 by 1 like I was the other day but it takes FOREVER.
